In the following piece of code, I am trying to get the handle for the
image I want to associate with the gadget.
static Boolean DrawGadget(FormPtr pFrm, UInt16 gadgetID)
{
Boolean bDrawn = false;
switch(gadgetID)
{
case CookieGadget:
{
UInt16 gadgetIndex = FrmGetObjectIndex(pFrm, gadgetID);
MemHandle hGadgetImage = DmGetResource(bitmapRsc,
bitmapCookieBtn);
BitmapType *gadgetImage = MemHandleLock(hGadgetImage);
RectangleType bounds;
// Get location of the gadget
FrmGetObjectBounds(pFrm, gadgetIndex, &bounds);
WinDrawBitmap(gadgetImage, bounds.topLeft.x, bounds.topLeft.y);
MemHandleUnlock(hGadgetImage);
DmReleaseResource(hGadgetImage);
}
bDrawn = true;
break;
}
return bDrawn;
}
I have to pass bitmapCookieBtn to DmGetResource() because that is the only
time it knows which image I am putting in the gadget, right? And, I
correctly get the location of the gadget in the form since gadgetIndex is
obtained from knowing which form and gadgetID, right? I just want to know
that I am not screwing anything here =)
